You can create e-mail messages with restricted permission using Information Rights Management only in Microsoft Office Professional Edition 2003 and Microsoft Office Outlook 2003.
I was able to access an e-mail message with restricted permission previously, but now I can't.
I replied to an e-mail message with restricted permission, but the original message wasn't included.
When you receive an e-mail message with restricted permission, you must obtain an Information Rights Management (IRM) license in order to read the message. The sender of the message chose to restrict permission for the message by using a Microsoft Windows Rights Management server that uses Microsoft Passport for authentication.
If you receive a message with restricted permission applied by the sender using Passport for authentication, you must obtain a Passport for the e-mail address the sender used to contact you. After you have obtained a Passport for this e-mail address, when you open the message, you will be prompted to verify your credentials for the message. Then you will receive a Rights Management license, and you can read the message.
I can't open an e-mail message with restricted permission when I am working offline.
In some cases, e-mail messages with restricted permission require you to connect to the Internet to verify your credentials and confirm that you have been given permission to read the message. After you have verified your credentials for a document, workbook, or presentation for the first time, you will be able to open the message at a later date, including when you are working offline, without having to connect to the Internet again.
An attachment I included in a message with restricted permission now has restricted permission too.
When you compose an e-mail message with restricted permission and include attachments, by default Microsoft Office 2003 documents, workbooks, and presentations that do not have restricted permission inherit the permission for the message. You can also restrict permission on Office 2003 attachments before attaching them to the e-mail message. In this scenario, permission for a document, workbook, or presentation might be different when people open it.
Other attachments that do not support restricted permission can be accessed by anyone who has permission to open the message. Because these attachments do not support restricted permission, the recipient will have full access to the attachment after the message is opened.
